Flowise: RCE via NodeVM Sandbox Escape in executeJavaScriptCode() nodeVMOptions Override

Summary A sandbox escape vulnerability in executeJavaScriptCode allows any authenticated user to execute arbitrary system commands as root on the Flowise server. The function accepts caller-provided nodeVMOptions that override the default sandbox security settings via JavaScript's spread operator...

CVE-2026-69254 Flowise: RCE via NodeVM Sandbox Escape in executeJavaScriptCode() nodeVMOptions Override

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.3, executeJavaScriptCode accepted caller-provided nodeVMOptions and merged them over the default NodeVM security settings in packages/components/src/utils.ts. An authenticated attacker reaching...

GHSA-48QW-824M-86PR ArcadeDB: Privilege escalation via reader role in /api/v1/command JS scripting language — arbitrary host file read

Impact A user holding only reader read-only privileges on a single database could execute arbitrary JVM code by sending a "language": "js" command to the POST /api/v1/command/database HTTP endpoint, and use it to read arbitrary files on the host filesystem e.g. /etc/passwd, configuration files,...

CVE-2026-46442

Flowise prior to v3.1.2 exposes an unauthenticated route POST /api/v1/node-custom-function that can accept arbitrary JavaScript in a Custom JS Function node. If E2B_APIKEY is not configured, code runs in a NodeVM sandbox and can be escaped to reach host process and execute system commands, enabli...
